Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a cardless power sensor which is easy to install. Background Art

[0002] In smart hotel guest control systems, the cardless power access solution relies on the combined detection and identification of multiple sensors, providing a smart cardless power access experience. For example, infrared sensors, primarily used to sense and identify human movement, collect detection data output by infrared probes and, through precise algorithms, accurately detect human movement within the detection area (motion detection). For example, radar sensors, primarily used to sense and identify human presence, utilize 24GHz microwave signals and are designed using Doppler radar principles. Through precise algorithms, they accurately detect the presence of humans within the sensing area (motion detection / static detection). Both detection results are transmitted to the host computer via RS485 communication signals, Bluetooth, or dry contact signals, transmitting the identification status. Based on the sensor detection data, the host computer activates the corresponding scenario or uses it as a user / user determination data for cardless power access applications. However, in hotel scenarios, these sensors are susceptible to interference from accidental touches by people on the bed. Utility Model Content

[0013] Figure 2 This is a schematic diagram of the installation location of the cardless power sensor for easy installation. DETAILED DESCRIPTION

[0014] The present invention is further described in detail below in conjunction with specific embodiments.

[0015] The cardless power sensor of this embodiment is easy to install. Figure 1 As shown, it includes an upper shell 4 and a lower shell 1 that interlock with each other. The upper shell 4 is provided with multiple external claws 42 on its outer periphery, and the lower shell 1 is provided with multiple external latches 12 on its outer periphery. The multiple external claws 42 of the upper shell 4 correspondingly engage with the multiple external latches 12 of the lower shell 1, thereby fastening the upper shell 4 to the end of the lower shell 1. The cardless power sensor also includes a bracket 2 mounted between the upper shell 4 and the lower shell 1, and a mounting sensor 3. The sensor 3 is mounted on the side of the bracket 2 near the upper shell 4. The sensor 3 is provided with a mounting portion for connecting to the bracket 2. The outer surface of the sensor 3 is provided with threads, and the inner surface of the mounting portion is provided with corresponding mating threads. The sensor 3 is specifically connected to the bracket 2 via the threaded connection mounting portion.

[0016] A through-hole 41 is axially defined in the center of the front face of the upper shell 4, into which the bracket 2 is inserted. The sensor 3 is housed within the upper shell 4, embedded within the through-hole 41. The sensor 3's sensing receiving position is exposed outside the upper shell 4 through the through-hole 41. In this position, the sensor 3 is partially obscured by the through-hole wall, limiting its sensing range. The bracket 2 is mounted within the lower shell 1 with an adjustable depth of insertion. The depth of insertion is proportional to the extent to which the sensor 3's sensing range is limited by the through-hole wall. The depth of embedding in the lower shell is adjustable, which means that: the inner wall of the lower shell 1 is provided with a plurality of inner clips 11 in an array, and a circle of inner claws 21 is provided on the circumference of the bracket 2 corresponding to the radial row of inner clips 11. This circle of inner claws 21 are together snapped into the same row of inner clips 11 to fix the bracket 2 in the lower shell 1; the inner clips 11 and the inner claws 21 are detachably connected, and the farther the inner clips 11 into which this circle of inner claws 21 are snapped are from the upper shell 4, the deeper the bracket 2 and the sensor 3 are embedded in the lower shell 1.

[0017] After checking into the room, Figure 2 As shown, the depth of the bracket 2 and the sensor 3 embedded in the lower shell 1 can be adjusted by yourself. The deeper the sensor 3 is embedded in the lower shell 1, the less likely the sensor 3 will sense the human body information of the person sleeping on the bed, until the sensing range of the sensor 3 is adjusted to be limited to the bedside table area. After adjustment, the boundary of the sensing range of the sensor 3 retreats from the original Q on the bed to P on the bedside table. The sensor 3 will not sense the human body information of the person sleeping on the bed, avoiding the passenger on the bed from accidentally triggering the sensor on the bed, thereby reducing the interference of false touch.

[0018] The sensor of this embodiment includes one or both of a wireless infrared sensor and a radar sensor.

[0019] The above is only an embodiment of the invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention and still fall within the scope of patent protection.
